Who do you see potentially being appointed to the Supreme Court in the future?
Wikipedia maintains a list of
Trump candidates. Not sure who would be the finalists for the next appointment. The finalists for the last appointment (Raymond Kethledge, Thomas Hardiman, and Amy Coney Barrett) could all be in the mix, but I could also see Trump turning to someone whom he'd previously appointed to an appellate court.
For Democrats, it obviously depends on who is president (and who controls the Senate), but Sri Srinivasan, Paul Watford, Jacqueline Nguyen, and Goodwin Liu all seem like likely contenders.
